Check Digit Verification of cas no

The CAS Registry Mumber 124960-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,6 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 124960-56:
(8*1)+(7*2)+(6*4)+(5*9)+(4*6)+(3*0)+(2*5)+(1*6)=131
131 % 10 = 1
So 124960-56-1 is a valid CAS Registry Number.

Tannins and Related Compounds. LXXXV. Structures of Novel C-Glycosidic Ellagitannins, Grandinin and Pterocarinins A and B

Nonaka, Gen-ichiro,Ishimaru, Kanji,Azuma, Ryutaro,Ishimatsu, Makoto,Nishioka, Itsuo

, p. 2071 - 2077 (2007/10/02)

The structures of three hydrolyzable tannins, i,e,, grandinin (3) (isolated from various species of Myrtaceae, Fagaceae and Lythraceae), pterocarinin A (4) (from Pterocarya steroptera C.DC. and Eucalyptus viminalis LABILL.) and pterocarinin B (6) (from P. stenoptera), have been established on the basis of chemical and spectroscopic evidence as novel C-glycosidic ellagitannins in which a C5-polyalcohol unit with lyxose-type configuration is linked through a carbon-carbon bond to the C-1 position of the C-glycosyl mioety.Successful biomimetic synthesis of 3 and 4 suggest that the C5-polyalcohol unit is biosynthetically derived from L-ascorbic acid.
